Today I installed the KDE2.2 beta1, but experienced problems with KSycoca and some none existing MIME types.

The packages are the SuSE 7.1 rpm´s and were installed completly. KSycoca said something like wrong Version number ... expect version 28...
Actually I couldn´t do anything. Kicker didn´t display any app and via Alt+F2 commands didn´t function. As I started Konqueror it just come up with a message like:"http is not supported"

unless you are interested in seeing how KDE starts up the first time its run, this is usually not necessary.

in the past, it has happened that certain config files have become corrupted to the point of crashing some app (hopefully this weakness is being fixed with a new check summing class to piggyback on the reading of the file) and that particular config file needed to be removed. sometimes when it is especially difficult to figure out which file is the offender or the user is particularly lazy/not attatched to their settings they will remove all of .kde ...

i have a rather ancient .kde, run KDE2 from CVS and the worst i've had to do is rm a file or two that got corrupted... and as a "bonus" it was always pretty obvious which file it was that i should delete =)

The GPL does prohibit distributing binaries linked to proprietary libraries such as free-beer QT for Windows. One solution would be to distribute source only. A user is allowed to link GPL'd code against whatever she wants, so long as it is not redistributed in binary form. Someone could even write a wrapper app to do the compilation and installation and release it under LGPL or some other license that permits linking against the libraries.

Of course, that only works for someone with all the stuff necessary to compile it, but still... it would be nice for the coolness factor of having KDE running natively under Windows, even if it wasn't tremendously useful for end users. Having the sources available might also help companies who could afford QT licenses and wanted to standardize on a KDE desktop internally, even on their windows boxes. Again, as long as they don't distribute it, the GPL doesn't care.
